With the help of SPSS software, the six main components of hot spot were analyzed by means of factor dimension reduction method, including the rational construction of digital library resource under the big data, the data structure of innovation, cloud computing and big data technology, knowledge service model, knowledge resource integration service, future development of the planning and innovation strategy. Through the analysis of relevant hotspots, the emerging research value points were continued to dig to promote the sustainable development of digital library in the future environment of big data.
